AIn operation, therefore, the lug 26 is nor-l mally in engagement with vthe block 27 and the wire to be bent is laid uponthe table' and inserted between the bendingmembers 13 and 14. The 'pedal 25 is then depressed which moves the shaft 10 longitudinally to throw the friction members into engagement with the disk 16 and rotate the disk 18 and the bending members until the ca m surface 33 of the lug 28 comes into engagement with the screw 32 wherebythe disk 18 is moved slightly away from the disk 16 to preventfurther rotation but still heldinVV i vided with wire ,bending members gf a pulley rotatable upon the shaft; a disk rigidly mountedupon the shaft; friction members interposed between the disk and the'pulley; manual means to move the shaft longitudi- V4nally Vto bring the friction .members into ed to limit the movement of the disk in the v opposite direction;

gripping action between theL disk and the pulley; a permanently fixed stop to limit the movement of the disk in one direction; and an adjustable stop carried by the disk adaptopposite direction.-

2. In a wire bending machine, a shaft provided with wire bending members; a` pulley` rotatable upon the shaft; ja disk rigidly mounted upon the shaft; a clutch inter.

posed between the disk and the pulley; manual means to move the shaft longitudinally to bring. the clutch into grippingaction; a stop and block to limit the rotation ofthe disk in one direction; av set-screw insaid block, and an adjustable stop carried by the disk and having a cam face adapted to strike said screw on the rotation'of the disk,l in the 3. VIn a wire bending machine, a journaled shaft; wire bending members carrled by the`v shaft; a driving disk loosely mounted upon` the shaft; a secondgdisk rigidly mounted upon the shaft, clutch members interposed between the disks; means to manually move the shaft longitudinally to bringinto action the clutch members; a spring embracing the shaft and adaptedto return the shaft to normal position; a stop carried. by the disk adapted to limit the movement of the disk adaptedV to limit the movement of the disk in one direction under the action ofthe spring; and an adjustable stop carried by the disk vin the opposite direction.

t.' In a bending machine, a shaft having bending members, a driving member rotatable upon the shaft, a disk fast on the shaft near said member, clutch 'elements interposed between the'disk and member,'and

means for moving the shaft longitudinally to bring the clutch elements into action; combined'with a second disk adjacent the first loose on the shaft and having a slot concentricwiththelatter, adjusting devices A in the first disk engaging said slot, a stop on said second disk, and a bloc-k with which the stop engages to vlimit the rotation of the disks'and shaft, for the purpose set fort-h.

' 5. In a wire bending machine, a journ'aled shaft; bending members carried Aby the shaft; al driving member rotatable upon the shaft; a disk carried rigidly by the shaft;

clutch members interposed between the disk and the driving member ;.means to move theA shaft longitudinally to bring the clutch members into action; a 'spring'embracing the sha-ft and adapted to return4 the disk to 'normal position; a rigidly positioned stop adapted to limit the movement ofthe disk l' in one direction; and av cam member carried by the disk adapted to release 'the clutch members at the of rotation. v

6. 'In a wire bending machine, a shaft journaled inV a frame, bending members car-, V

ried' by 'the shaft, a driving member rota table upon the shaft, a disk carried rigidly by the shaft, clutch membersinterposed between the disk and the driving member,l

means to move the shaft longitudinally to bring the clutch 'members into action, a

coiled spring embracing the shaft'and con-fy nected with the frame and disk, the spring acting to return the disk to normal position, a stop on the diskadapted to limit the rotation of the disk in one direction, a second disk adjustably mounted on the first, and

a cam carried by' the second disk adapted to' end of apredetermined arc release the clutch members at' the end "of af i predetermined arcV o f rotation. v
